Neuropsychiatric Symptoms Mimicking Dementia In A Patient Treated With Imatinib, Ashley Jones, Samuele Bonomi, Keith E Stockerl-Goldstein, Randall J Bateman

2020-Current year OA Pubs

Tyrosine kinase inhibitors are the cornerstone of chronic myeloid leukemia treatment. Newer agents have more potency and a broader spectrum of action, but also a higher potential for neuropsychiatric side effects. We present a case of a patient on imatinib who developed progressive cognitive, mood, and behavioral alterations. He was investigated for dementia and psychiatric disorders but ultimately improved only after discontinuing imatinib. His decompensation years after therapy start, followed by complete and rapid remission, is atypical. We also review the most recent neurobiological findings on the role of tyrosine kinase alterations in dementia and their importance for mood regulation.

Apoe-Stratified Proteomic And Metabolomic Analysis Reveals Mitochondrial Dysfunction Inflammation And Lipid Dysregulation In Alzheimer's Disease, Fuhai Li, Yike Chen, Daniel Western, Muhammad Ali, Menghan Liu, Katherine Gong, Ying Xu, Joseph Lowery, David M Holtzman, Carlos Cruchaga, Et Al.

2020-Current year OA Pubs

Apolipoprotein E (APOE) ε4 is the strongest genetic risk factor for Alzheimer's disease (AD). However, it is known that other pathways independent of APOE also play a role in AD. Disentangling APOE-dependent and independent effects is instrumental for understanding the biology of AD. We conducted an APOE-stratified multi-omic analysis in multiple large datasets to identify AD-associated plasma proteins and metabolites. More than 64% of the identified proteins were not found in non-APOE stratified studies, and 17% of the proteins showed APOE-specific trends. Mitochondrial dysfunction was associated in AD independently of APOE and was accompanied by disruptions in glucose and lipid …

A Pathogenic Tau Mutation Drives Autophagy-Lysosome Dysfunction That Limits Tau Degradation In A Model Of Frontotemporal Dementia, Farzaneh S Mirfakhar, Jacob A Marsh, Chihiro Sato, Kylie J Schache, Miguel A Minaya, Roland E Dolle, Stephen C Pak, Gary A Silverman, David H Perlmutter, Shannon L Macauley, Celeste M Karch

Tau accumulates in a group of neurodegenerative diseases known as tauopathies. A prevailing hypothesis has been that Tau degradation is impaired due to an age-related imbalance in the autophagy-lysosome pathway, but whether these defects are a cause or consequence of Tau accumulation remains unclear. Here we show that a disease-causing mutation in the MAPT gene, which encodes Tau, p.R406W, is sufficient to disrupt multiple steps of the autophagy-lysosome pathway in human neurons. Using Airyscan super-resolution imaging, we find that mutant Tau neurons accumulate Tau and phosphorylated Tau in dysfunctional lysosomes, exhibit reduced lysosome motility, impaired fusion of autophagosomes and lysosomes, …

BACKGROUND: Previous studies on intraventricular hemorrhage (IVH), a common and severe complication of preterm birth, and subsequent post-hemorrhagic hydrocephalus (PHH), have predominantly concentrated on the secretory function of the choroid plexus (ChP), with considerably less emphasis on its barrier function. We hypothesized that PHH is associated with immune-related alterations in the junction biology of ChP. METHODS: We examined differences in tight junctions and macrophages using a neonatal mouse model of PHH (n = 40) and in vitro ChP explants (n = 22), as well as human post-mortem samples (n = 6). To test our hypothesis, we employed histology, immunofluorescence, magnetic …

2020-Current year OA Pubs

Ketone bodies have traditionally been recognized as glucose-sparing energy sources, with hepatic ketogenesis and peripheral ketolysis serving pivotal functions in maintaining energy homeostasis during fasting. Although they are commonly seen as harmful due to their link with ketoacidosis, recent studies emphasize their roles in organ protection. This has sparked interest in their possible use as a treatment for chronic kidney disease (CKD). In this study, we examined both exogenous and endogenous ketone body supplementation in adenine-induced kidney injury in mice. Supplementation with the ketone body precursor 1,3-butanediol significantly improved adenine-induced renal fibrosis, inflammation, and apoptotic cell death. However, genetically deleting …

Energetic Diversity In Retinal Ganglion Cells Is Modulated By Neuronal Activity And Correlates With Resilience To Degeneration, Zelun Wang, Christopher Zhao, Shelly Xu, Minglei Zhao, Sean Mccracken, Rajendra S Apte, Philip R Williams

2020-Current year OA Pubs

Neuronal function requires high energy expenditure that is likely customized to meet specific signaling demands. However, little is known about diversity of metabolic homeostasis among divergently-functioning types of neurons. To this end, we examined retinal ganglion cells (RGCs), a population of closely related, yet electrophysiologically distinct excitatory projection neurons. Using in vivo 2-photon imaging to measure ATP with single cell resolution, we identified differential homeostatic energy maintenance in the RGC population that correspond to distinct RGC types. In the presence of circuit activity, the most active RGC type (Alpha RGCs), had lower homeostatic ATP levels than other types and exhibited …

Glioblastoma (GBM) remains a lethal tumor, largely due to robust mechanisms that prevent effective induction of cell death. Ferroptosis, a form of iron-dependent cell death, is a promising vulnerability in GBM. Here, we demonstrate that lipocalin-2 (LCN2) suppresses ferroptosis in GBM cells via the receptor tyrosine kinase AXL. LCN2 was elevated in GBM cells compared to lower-grade tumor and non-transformed cells, and Lcn2 knockdown impaired GBM cell fitness and growth in vitro and in vivo. Mechanistically, Lcn2 knockdown triggered ferroptosis, which was specifically rescued with ferroptosis inhibitors but not apoptosis or necroptosis inhibitors. Lcn2 knockdown reduced AXL phosphorylation, which was …

2020-Current year OA Pubs

BACKGROUND: Romantic relationships are important contexts for substance use and emotional well-being. We tested the hypotheses that (i) genetic predispositions for alcohol consumption would be positively associated with partner substance use, (ii) partner substance use would moderate genetic influences on one's own alcohol outcomes, and (iii) partner discordance in substance use would be associated with lower emotional well-being and relationship quality.

METHODS: Analyses included 2,357 participants (M

RESULTS: Participant PGS

CONCLUSIONS: The results highlight the importance of partner substance use in etiological models of alcohol use, emotional health outcomes, and relationship quality.

Molecular Characterization Of Humanized Apoe Mouse Models Reveals Source And Genotype Dependent Differences, Na Wang, David M Holtzman, Et Al.

2020-Current year OA Pubs

BACKGROUND: Humanized APOE targeted-replacement (TR) mice are essential tools for studying apoE isoform effects in Alzheimer’s disease (AD) and other apoE-related disorders. Despite their widespread use, existing APOE mouse models, generated with different gene targeting strategies, have not been directly compared in terms of apoE isoform expression, lipid profiles, and transcriptomic signatures. Such differences could impact how we interpret APOE genotype-related outcomes, as well as related underlying molecular mechanisms. METHODS: We conducted a comprehensive molecular comparison of humanized APOE mouse models from three sources: Taconic Biosciences (TAC), the Cure Alzheimer’s Fund (CAF), and The Jackson Laboratory (JAX). We assessed apoE …

Glomerular Basement Membrane Structural Integrity Dictates Trans-Tissue Deposition Of Laminin In The Kidney, Kohei Omachi, Meei-Hua Lin, Pongpratch Puapatanakul, Joshua F Begin, Karen K Mckee, Hironobu Fujiwara, Peter D Yurchenco, Jeffrey H Miner

2020-Current year OA Pubs

Basement membranes (BMs) are specialized extracellular matrices (ECMs) essential for tissue structure and function. In non-vertebrates, ECM components can be produced both locally and by distant tissues. In contrast, mammalian ECM has traditionally been considered to originate predominantly from adjacent or tissue-resident cells. The kidney glomerular basement membrane (GBM), composed of laminin-α5β2γ1 and collagen-α3α4α5(IV), is produced by neighboring cells and functions as a filtration barrier. Alport syndrome, a genetic kidney disease, is characterized by GBM structural defects and ectopic laminin-α2 deposition, but the source of this laminin remains unknown. Here, using CRISPR-Cas9 transgenic models, we demonstrated that ectopic laminin-α2 in …

2020-Current year OA Pubs

INTRODUCTION: Genetically engineering human pluripotent stem cell (hPSC)-derived islets is a promising strategy for improving transplantation for diabetes cell therapy; however, genetic perturbations that modulate transplantation outcomes have yet to be systematically explored.

METHODS: To identify potential targets, we performed an unbiased whole-genome CRISPR-activation screen in transplanted stem cell-derived islets (SC-islets). Specifically, we created a stem cell line with CRISPR-activation components (HUES8-VPR) and then transduced these stem cells with a lentiviral guide RNA library targeting the whole human genome. Following transduction, the stem cells were differentiated into SC-islets, which were subsequently transplanted into NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJ (NSG) immunodeficient mice. After transplantation, SC-islets …

Multi-kilobase knock-ins (KIs) are a necessary, yet challenging type of genome editing to create and characterize in cell lines and animals. The combination of rAAV donor transduction and electroporation of single-cell mouse embryos with Cas9/gRNA ribonucleoprotein complex enables highly efficient KI, but the insert size is limited by the viral packaging capacity. Here, we report the creation of up to 6.7 kb precise KI achieved in one step by using three rAAVs designed to insert one after the other. To fully characterize the edited genome with large KIs, we developed LOCK-seq (LOng-read sequencing of Captured Kilo-base targets), where relevant genomic …
